Two of my colleagues have committed suicide.

I remember a Peanuts cartoon where Linus (7) and Charlie Brown (9) are leaning over the picket fence considering life.
Linus asked "Do you think there's one day on your life that's better than any other?"
Charlie Brown replied "There must be."
Linus paused then said "Suppose you've already had it".

For my colleagues who committed suicide I imagine that their last day was also their worst day.
We will have no way of knowing.

But looking on the brighter side, for me at least, there's a 60% chance that if I've had the best day of my life it was while working for IBM.

Brighter still, I hope my best day is still some time in the future.
